Hello,All the script samples I use for WRF output plot several fields in a loop. I would like to plot just one variable at any given time step and a given level.With my script below, my T is T(T,L,L,L), i.e. T(Time,Level, Lat,Lon)=T(17,31,60,69).When I run the code below I get a plot, but alos the error: The use of this software is governed by a License Agreement. See http://www.ncl.ucar.edu/ for more details.(0) check_for_y_lat_coord: Warning: Data either does not contain(0) a valid latitude coordinate array or doesn't contain one at all.(0) A valid latitude coordinate array should have a 'units'(0) attribute equal to one of the following values: (0) 'degrees_north' 'degrees-north' 'degree_north' 'degrees north' 'degrees_N' 'Degrees_north' 'degree_N' 'degreeN' 'degreesN' 'deg north'(0) check_for_lon_coord: Warning: Data either does not contain(0) a valid longitude coordinate array or doesn't contain one at all.(0) A valid longitude coordinate array should have a 'units'(0) attribute equal to one of the following values: (0) 'degrees_east' 'degrees-east' 'degree_east' 'degrees east' 'degrees_E' 'Degrees_east' 'degree_E' 'degreeE' 'degreesE' 'deg east'

I have seen a number of posts on ncl-talk on this error, but I do not understand the solutions given.When I put the following code after addfile
